Supplier:
Anaspec Inc
Description:
This peptide is histone H4 amino acid residues 1 to 21. It is asymmetrically dimethylated at Arg3 with both methyl groups added to one nitrogen of the guanidinium group, and also contains a C-terminal GG linker, followed by a biotinylated Lys. Methylation of histone H4 at Arg3 is an important step in transcriptional activation, and allows for subsequent acetylation of H4 tails by p300. Provided at >95% peptide purity, this peptide was dissolved in distilled water at 1 mg/ml and re-lyophilized to powder form.

Supplier:
Anaspec Inc
Description:
This peptide is histone H4 (1-23) symmetrically dimethylated at Arg3 followed by a biotinylated Lys conjugated to a C-terminal GG linker. Methylation of Arg3 is catalyzed by PRMT1 and functions to promote p300 acetylation of histone H4. It has also been shown to regulate transcriptional activation of genes involved in cholesterol and bile acid homeostasis. Provided at >95% peptide purity, this peptide was dissolved in distilled water at 1 mg/ml and re-lyophilized to powder form.

Description:
A mineral oil is any of various colorless, odorless, light mixtures of alkanes in the C15 to C40 range from a non-vegetable (mineral) source, particularly a distillate of petroleum. Most often, mineral oil is a liquid by-product of the distillation of petroleum to produce gasoline and other petroleum-based products from crude oil. A mineral oil in this sense is a transparent, colorless oil composed mainly of alkanes and cyclic paraffins, related to petroleum jelly (also known as "white petrolatum").

Description:
This peptide is histone H3 (1-24) acetylated at Lys14, Lys18, and Lys23, with a C-terminal GG linker followed by a biotinylated Lys. Hyperacetylation of histone H3 plays a role in chromatin structure and transcriptional activation. Provided at >95% peptide purity, this peptide was dissolved in distilled water at 1 mg/ml and re-lyophilized to powder form.
Sequence:ARTKQTARKSTGG-K(Ac)-APR-K(Ac)-QLAT-K(Ac)-A-GGK(Biotin) MW:3149.7 Da % peak area by HPLC:95 Storage condition:-20° C
Catalog Number:
(103008-596)
Supplier:
Anaspec Inc
Description:
This peptide is Histone H3 (21-44). It is acetylated at lysine 36 with a C-terminal G linker followed by a biotinylated lysine. The acetylation of histone H3 at lysine (K) 36 is highly conserved in mammals and is mainly localized to the promoters of RNA polymerase II-transcribed genes. The transition between the acetylation and methylation of K36 acts as an “acetyl/methyl switch”, controlling chromatin function along transcription units. Provided at >95% peptide purity, this peptide was dissolved in distilled water at 1 mg/ml and re-lyophilized to powder form.
Sequence:ATKAARKSAPATGGV-K(Ac)-KPHRYRPG-GK(Biotin) MW:2959.5 Da % peak area by HPLC:95 Storage condition:-20° C
Catalog Number:
(PI51101)
Supplier:
Thermo Fisher Scientific Chemicals Inc.

Catalog Number:
(103009-086)
Supplier:
Anaspec Inc
Description:
This peptide is histone H4 (1-25) with acetylation at Lys12 and Lys16 and trimethylation at Lys20, followed by a C-terminal GSGS linker and a biotinylated Lys. Trimethylation at Lys20 of histone H4 is catalyzed by Suv4-20 and is involved in transcriptional silencing and heterochromatin formation in eukaryotes. It has been shown that histone H4 is preferentially acetylated first at Lys16, then at Lys12. Diacetylated histone H4 has been shown to bind repressor protein TUP1. Acetylation of histone H4 also regulates heterochromatin formation by promoting the binding of bromodomains to p300 and transcription factor TAFII250 and inhibiting interactions with SIR3. Provided at >95% peptide purity, this peptide was dissolved in distilled water at 1 mg/ml and re-lyophilized to powder form.

Catalog Number:

Supplier:
Anaspec Inc
Description:
This peptide is histone H3 with acetylation at Lys4. It is biotinylated through a C-terminal GGK linker. This post-translationally modified histone peptide is found in humans, Tetrahymena thermophila, Schizosaccharomyces pombe , and mice. Acetylation at Lys4 is controlled by Mst1. This peptide acts as a chromodomain switch by weakening the interaction between Chp1 and the H3K9 methylated tail, thus facilitating binding of HP1 proteins. Provided at >95% peptide purity, this peptide was dissolved in distilled water at 1 mg/ml and re-lyophilized to powder form.

Description:
It is known that phenol and p-cresol are promoters of skin tumors and also urinary excretion of phenol and p-cresol is increased by exposure to benzene, which has hemopoietic toxicity, and toluene, respectively. Therefore, the determination of phenol and p-cresol is important in clinical chemistry and toxicology. Because phenol and p-cresol are present in urine as sulfate or glucuronide conjugates, they are hydrolyzed enzymatically or with acid, followed by distillation or extraction with organic solvent prior to measurement by GC or HPLC. However, these GC and HPLC methods require relatively large sample volumes (more than 1 ml) because of their insufficient sensitivities for measuring small amounts of phenol and p-cresol. The application of fluorescent labeling techniques to HPLC result in a sensitive and selective method. Phthalimidylbenzenesulfonyl chlorides habe also been successfully used for high sensitivity labelling of amino acids prior to HPLC.
